SELF-VENTILATING BUNG.

SPECIFICATION forming part of Letters Patent No. 263,259, dated August 22, 1882.

Application filed J une 3, 1882. (No model.)

To all whom it may concern:

Beit known that I, WM.A.VREELAND, acitizen of theUnited States. and aresidentofBrooklyn, in the county of Kings and State of New York, have invented a new and valuable Improvement in Self-Ventilating Bungs; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a partof thisspecificatin,aud to the letters and figures of reference marked thereon.

Figure l isa perspective view of the tapering Fig. 2 is a bottom view of the bung. Fig.3 is avertical sectional view of the bung. Fig. 4 is a detached View of the valve, and Fig. 5 is a plan view of the guard.

This invention relates to selfventilating bungs; and it consists in the construction and novel arrangement of parts-viz., the hollow tapering metallic core having spurs upon its outer surface and a flanged pipe or neck extending from its lower end, in combination with an in versely-tapered packing or surrounding wall, a rubber valve slitted in its pointed extremity, and a convex cross-shaped guard located in the bottom of the tapering hollow of the metallic core, as will be hereinafter fully described, and pointed out'in the claim.

In the accompanying drawings, the letter a designates the metallic core provided with the spurs a; b, the surrounding packing ofrubber or other suitable material. Within the core a is the recess 0, the same being tapered toward its outer end for the purpose of affording a purchase to-the lever used for prying out the bung. Through the bottom of the recess is the airpassage 01, which extends from the inner external surface of the bungin the form of apipe, and isa partof the casting of the metalliccore. Over this air-passage in the recess 0 is the guard 6, having bearings g and notches h, to allow of the admission of air through the airpassage over which it rests. The valve shown at n is a pouch with a slit at the lower end, the edges or lips of which, impinging upon each other, allow of vent or stoppage, as required. The upper end is bound upon the pipe through which. the air passes.

Having described my invention, what I claim, and desire to secure by Letters Patent, is-

In a self-ventilating bung, the hollow tapering metallic core to, having the spurs a, recess a, and flanged pipe or neck having air-passage d, in combination with the rubber packing I), the valve 1 slitted in its point, and the crossshaped guard g h, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

WILLIAM A. VREELAND.
